DNA/RNA Flashcards
DNA is double stranded, with the strands held together by hydrogen bonds between the nitrogenous bases
Base pair rules:
A pairs with T
G pairs with C
RNA pairing rules
A-U
G-C
The nitrogenous bases of DNA are:
Adenine
Guanine
Cytosine
Thymine
DNA replication
The process by which DNA is copied
Relies on the base pair rules
The RNA bases are
Adenine
Guanine
Cytosine
Uracil
RNA base pairs are
A-U
G-C
(3) types of RNA participate in protein synthesis
mRNA
tRNA
rRNA
mRNA
Messanger RNA
Carries the recipe for making protein
tRNA
Transfers the recipe
rRNA
Ribosomal build the amino chain
Condos
Sets of (3) nucleotides that code for specific amino acids
Translation initiation
Begins when small ribosomal subunit binds to the beginning of mRNA
Translation elongation
The next tRNA binds with the next codon
Translation determination
Elongation continues until the ribosome encounters a stop condon
The stop condons are:
UAA, UAG and UGA
